Of course, but it has a significant, fundamental impact on huge aspects of "the economy" as we know it. Large segments of commerce - particularly in the U.S. - pivot heavily on people spending time and money commuting, spending time in an office, eating and drinking at nearby establishments, etc.
Overpriced coffee shops (not Central Perk style ones in neighbourhoods - takeaway chain ones)

The trains will be interesting - especially in London. UK rail infrastructure is built to cope with large numbers of peak time commuters travelling with large discounts. That infrastructure won't vanish, but the income will (a £3k a year discount for a season ticket still means you're paying £4k a year - if that goes, times a million, it's a lot of operating revenue with little drop in costs)
Certainly not. I don't think it's bad either, but some people (owners of expensive offices) do.
